Physical Properties: It is an organosilane with dual functional groups: reactive amino groups and hydrolyzable inorganic methoxysilyl groups. It is a colorless liquid with characteristic ammonia odor, soluble in solvents such as alcohols, aliphatic hydrocarbons and aromatic hydrocarbons.

Synthesis Method

Allyl chloride reacts with trichlorosilane to obtain chloropropyltrichlorosilane, then reacts with methanol, followed by amination and separation to obtain the product.

Applications

1. Glass/Electronic cloth composites: Used as a whole or as a component of sizing agents.

2. Used as a primer for glass and metal surfaces.

3. Foundry resins: Used as an additive for cold-curing phenolic resins and furan resins.

4. Used in the synthesis of amino silicone oil and its emulsions.

5. Excellent adhesion promoter for polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials. It improves pigment dispersion and adhesion to glass, aluminum, iron and other metals, and is also suitable for polyurethane, epoxy and acrylic latex coatings.

6. Amino and methoxy groups are used to couple organic polymers and inorganic fillers respectively, enhancing their adhesion and improving the mechanical, electrical, water resistance and aging resistance properties of products. Applied to mineral-filled thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide, carbonate, etc., it can greatly improve the physical and mechanical properties (dry and wet flexural strength, compressive strength, shear strength) and wet electrical properties of reinforced plastics, and improve the wettability and dispersion of fillers in polymers. In resin sand casting, it enhances the adhesion of resin silica sand and improves the strength and moisture resistance of molding sand. In the production of glass wool and mineral wool, adding it to phenolic adhesives improves moisture resistance and compressive resilience.

Storage & Transportation

Store in a ventilated and dry environment, seal the bottle cap tightly to prevent moisture absorption (Strictly prohibited to store with acids, flammable substances, reducing agents, etc.).

Packaging
